T 0 all whom it may concern:

Be it known that I, FRANKLIN A. ESPE- LAND, a citizen of the UnitedStates of America, residing at Oakes, in the county of Dickey and Stateof North Dakota, have invented certain new and useful Improvements inScrubbing-Machines, of which the following is a specification.

The present invention relates to an improved scrubbing machine,especially designed for domestic use in scrubbing floors, or othersurfaces, and is of that type having a self contained reservoir fromwhich the water is taken and carried to the floor by successive wiperson a rotary device operated from the traction or supporting wheels ofthe machine, and the machine is hand operated in a manner similar tocarpet sweepers of this type.

The primary object of the invention is a scrubbing machine in which areservoir is involved and from which the water required to scrub thefloor is taken by successive wipers, without unnecessary loss of waterfrom the tank, or reservoir, and without spilling the water, and to thisend the invention consists in certain novel combinations andarrangements of parts in the construction of the machine as will behereinafter described and claimed.

Figure 1 is a side view of a machine embodying the invention.

Fig. 2 is a vertical, central longitudinal sectional view of thereservoir and rotor.

Fig. 3 is a perspective view of one of the blades and its wiper.

Fig. 4: is a detail view showing, partly in section, the handle andframe construction for supporting the actuating parts of the machine.

In the preferred form of the invention as depicted in the drawings, thetank or reservoir 1 is preferably of metal, and water tight to containthe water that may be furnished through the inlet 2, and within the tanka transverse baffle plate 3 is arranged at an incline to prevent unduesplashing of the water and restrict the movement of the body of thewater, as a whole.- A second partition 4 is provided and extendstransversely of the tank, the partition being curved as shown and at itsupper end 5 arranged to leave a passage below the top of the tank, whileat the bottom, at 6, the partition has a reverse bend adjacent thebottom opening 7 formed etween t served p ion and Specification ofLetters IiPatent.

the outwardly curved end wall 8 of the tank.

The end 9 of the wall 8 is bent as shown to form a flange at the edge ofthe opening 7 and a rubbing device is formed of sheet rubberlO that isfolded and clampedon the tank by means of the clamping strip 11extending across the tank, and the clamp.

screws '12. I

The whole device is supported onthe pairs of rollers or wheels 13 and'14, the latter wheels being the drive wheels fixed on the.

bolt 20 at the upper end of the post 21 fixed on and projecting abovethe side walls of the tank, while the lower end of the link 18 ispivoted on a transverse bar 22 (dotted 7 lines Fig. 1) that rigidlyconnects the two side bars 16. 7

Within the rounded end of the tank abov the opening 7 and operatingwithin the curved end wall 8 is a rotor including in its construction apair of end disks or round heads 25, and a tubular hub 24 fixed torevolve with the operating shaft 17 The rotor is fashioned to form fivebuckets 23 as shown and is provided with a similar number of wipers 26,the buckets being formed by, and the wipers attached to a series oftangentially extending transverse, metallic plates 27 each of which. hasa curved flange 28 to be attached to the hub 24. The plates are arrangedtangentially of the hub' and extend outwardly in close proximity to theperiphery of the enddisks 25, while at the ends of these plates flanges29 are provided forattachment to the end walls of the rotor, thusforming water tight 7 compartments'or buckets between adjoining plates,in connection with the walls of the tank. 1 V V The wipers 26 are ofsuitable material similar to that used formopping and scrubbing and theyextend the entire distance be.- tween the end disks 25, a binding strip30 and screws 31 being employed to retain the WiPQIS 0 the plate;operation of the i v rotor and its wipers will be clear from a study ofFig. 2, and it will be seen that the wipers pass the opening above thepartition 4, at 5, and flop over the partition top permitting water tosplash into the bucket 23 and also onto the wiper, and as these partsare rapidly revolving when the device is in operation, it will beevident that an excessive amount of water cannot splash into the rotor.The back and forth movement of themachine, as manipulated by theoperator, causes the water to splash about in the tank, and even whenthe Water becomes low in the tank, from continued splashing into the'open buckets as they pass the upper the usual handle 36 is provided forthe de- 7 vice.

What I claim is The combination with a casing formed with an open bottomcylindrical compartment having an upper opening communicating with asource of Water supply, of a shaft journaled in the walls of thecompartment, a hub and end disks on the shaft, tangentially arrangedplates carried by the hub and forming with the disks water receptacles,a Wiper attached at the outer free edge of each plate adapted to passover said upper and lower openings, and a rubber extending across thecasing adjacent to the bottom opening of the compartment.

In testimony whereof I afiix my signature.
